5) New sensors: Beyond the common choice of on-board sensors, such as cameras, IMU and LIDAR, the emerging new sensors provide an alternative to construct a more accurate and robust multimodal system. New sensors including event camera[1]}, thermo camera[2]}, mm-wave device[3]}, radio signals[4]}, magnetic sensor[5]}, have distinct properties and data format compared to predominant SLAM sensors such as cameras, IMU and LIDAR. Nevertheless, the effective learning approaches to processing these unusual sensors are still underexplored.
